2016-09-09ARM: pxa: remove irq init from dt machinesRobert Jarzmik1-3/+8
The init_irq and handle_irq can be declared through standard irqchip declaration and are not necessary in machine descriptions. This is another step towards the generic kernel for the pxa architecture. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Acked-by: Arnd Bergmann <arnd@arndb.de>

2016-02-01ARM: pxa: fix building without IWMMXTArnd Bergmann1-2/+4
When CONFIG_IWMMXT, the pxa3xx and pxa27x suspend/resume code emits some xscale specific instructions, which are rejected by the assembler, because gcc is built with -march=armv5 -mtune=xscale and passes that option to the assembler: /tmp/cciHumzr.s:553: Error: selected processor does not support ARM mode `mra r2,r3,acc0' /tmp/cciHumzr.s:605: Error: selected processor does not support ARM mode `mar acc0,r2,r3' make[3]: *** [arch/arm/mach-pxa/pxa3xx.o] Error 1 /tmp/cci5MUNu.s:326: Error: selected processor does not support ARM mode `mra r2,r3,acc0' /tmp/cci5MUNu.s:367: Error: selected processor does not support ARM mode `mar acc0,r2,r3' make[3]: *** [arch/arm/mach-pxa/pxa27x.o] Error 1 Overriding with -Wa,-march=xscale no longer works, so instead I'm adding an explict ".arch_extension" directive in all four inline assembly statements, which should work even if they end up in a different order in the assembly output.

2015-10-16ARM: pxa: remove incorrect __init annotation on pxa27x_set_pwrmodeArnd Bergmann1-1/+1
The z2 machine calls pxa27x_set_pwrmode() in order to power off the machine, but this function gets discarded early at boot because it is marked __init, as pointed out by kbuild: WARNING: vmlinux.o(.text+0x145c4): Section mismatch in reference from the function z2_power_off() to the function .init.text:pxa27x_set_pwrmode() The function z2_power_off() references the function __init pxa27x_set_pwrmode(). This is often because z2_power_off lacks a __init annotation or the annotation of pxa27x_set_pwrmode is wrong. This removes the __init section modifier to fix rebooting and the build error.

2015-09-05rtc: pxa: convert to use shared sa1100 functionsRob Herring1-1/+0
Currently, the rtc-sa1100 and rtc-pxa drivers co-exist as rtc-pxa has a superset of functionality. Having 2 drivers sharing the same memory resource is not allowed by the driver model if resources are properly declared. This problem was avoided by not adding memory resources to the SA1100 RTC driver, but that prevents clean-up of the SA1100 driver. This commit converts the PXA RTC to use the exported SA1100 RTC functions. Now the sa1100-rtc and pxa-rtc devices are mutually exclusive, so we must remove the sa1100-rtc from pxa27x and pxa3xx.

2015-07-18ARM: pxa: transition to dmaengine phase 1Robert Jarzmik1-0/+1
In order to slowly transition pxa to dmaengine, the legacy code will now rely on dmaengine to request a channel. This implies that PXA architecture selects DMADEVICES and PXA_DMA, which is not pretty. Yet it enables PXA drivers to be ported one by one, with part of them using dmaengine, and the other part using the legacy code. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>
2015-05-13ARM: pxa: Transition pxa25x and pxa27x to clk frameworkRobert Jarzmik1-172/+2
Transition the PXA25x and PXA27x CPUs to the clock framework. This transition still enables legacy platforms to run without device tree as before, ie relying on platform data encoded in board specific files. The transition breaks the previous clocks activation of pin control (gpio11 and gpio12). Machine files should be amended to take that into account. This is the last step of clock framework transition for pxa25x and pxa27x, leaving only pxa3xx for further work.

2013-01-08ALSA: pxa27x: fix ac97 warm resetMike Dunn1-2/+2
This patch fixes some code that implements a work-around to a hardware bug in the ac97 controller on the pxa27x. A bug in the controller's warm reset functionality requires that the mfp used by the controller as the AC97_nRESET line be temporarily reconfigured as a generic output gpio (AF0) and manually held high for the duration of the warm reset cycle. This is what was done in the original code, but it was broken long ago by commit fb1bf8cd ([ARM] pxa: introduce processor specific pxa27x_assert_ac97reset()) which changed the mfp to a GPIO input instead of a high output. The fix requires the ac97 controller to obtain the gpio via gpio_request_one(), with arguments that configure the gpio as an output initially driven high. Tested on a palm treo 680 machine. Reportedly, this broken code only prevents a warm reset on hardware that lacks a pull-up on the line, which appears to be the case for me.

2010-08-16Merge branch 'for-2.6.36' into for-2.6.37Mark Brown1-3/+4
Fairly simple conflicts, the most serious ones are the i.MX ones which I suspect now need another rename.

2010-08-12ASoC: multi-component - ASoC Multi-Component SupportLiam Girdwood1-0/+4
This patch extends the ASoC API to allow sound cards to have more than one CODEC and more than one platform DMA controller. This is achieved by dividing some current ASoC structures that contain both driver data and device data into structures that only either contain device data or driver data. i.e. struct snd_soc_codec ---> struct snd_soc_codec (device data) +-> struct snd_soc_codec_driver (driver data) struct snd_soc_platform ---> struct snd_soc_platform (device data) +-> struct snd_soc_platform_driver (driver data) struct snd_soc_dai ---> struct snd_soc_dai (device data) +-> struct snd_soc_dai_driver (driver data) struct snd_soc_device ---> deleted This now allows ASoC to be more tightly aligned with the Linux driver model and also means that every ASoC codec, platform and (platform) DAI is a kernel device. ASoC component private data is now stored as device private data. The ASoC sound card struct snd_soc_card has also been updated to store lists of it's components rather than a pointer to a codec and platform. The PCM runtime struct soc_pcm_runtime now has pointers to all its components. This patch adds DAPM support for ASoC multi-component and removes struct snd_soc_socdev from DAPM core. All DAPM calls are now made on a card, codec or runtime PCM level basis rather than using snd_soc_socdev. Other notable multi-component changes:- * Stream operations now de-reference less structures. * close_delayed work() now runs on a DAI basis rather than looping all DAIs in a card. * PM suspend()/resume() operations can now handle N CODECs and Platforms per sound card. * Added soc_bind_dai_link() to bind the component devices to the sound card. * Added soc_dai_link_probe() and soc_dai_link_remove() to probe and remove DAI link components. * sysfs entries can now be registered per component per card. * snd_soc_new_pcms() functionailty rolled into dai_link_probe(). * snd_soc_register_codec() now does all the codec list and mutex init. This patch changes the probe() and remove() of the CODEC drivers as follows:- o Make CODEC driver a platform driver o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core. o Removed all static codec pointers (drivers now support > 1 codec dev) o snd_soc_register_pcms() now done by core. o snd_soc_register_dai() folded into snd_soc_register_codec().
